Radius Manager: AAA Framework & Network Security Integration

This 200-word course provides a comprehensive exploration of the RADIUS (Remote Authentication Dial-In User Service) protocol, a cornerstone of network security and AAA (Authentication, Authorization, Accounting) frameworks. Designed for software engineers and network professionals, the curriculum demystifies RADIUS architecture, packet exchange workflows (e.g., Access-Request, Access-Accept/Reject), and its critical role in securing access to VPNs, Wi-Fi networks, and enterprise systems.Learn to configure RADIUS servers for centralized user management, integrating seamlessly with directories like LDAP and Active Directory. Delve into authentication methods (EAP, PAP, CHAP), certificate-based security (EAP-TLS), and encryption protocols to safeguard sensitive credentials. Practical modules include Wireshark-based packet analysis to diagnose authentication failures, latency issues, and protocol vulnerabilities. Explore RADIUS accounting for tracking user sessions and resource usage, vital for compliance (e.g., HIPAA, GDPR).The course emphasizes real-world applications: automating AAA workflows with Python scripts, deploying RADIUS in hybrid cloud environments (AWS/Azure), and enforcing dynamic access policies (VLAN assignments, QoS tagging). Hands-on labs simulate scenarios like mitigating rogue access points, troubleshooting RADIUS-DHCP conflicts, and hardening servers against brute-force attacks.Key Outcomes:Master RADIUS protocol mechanics and AAA implementation.Secure network access with advanced authentication/authorization controls.Troubleshoot and optimize RADIUS for scalability and compliance.Bridge software development with network security best practices.Prerequisites: Basic networking (TCP/IP, VLANs) and familiarity with Linux/Python.
